Smatch report warning as follows:
sound/soc/amd/acp/acp-platform.c:199 acp_dma_open() warn:
'&stream->list' not removed from list
If snd_pcm_hw_constraint_integer() fails in acp_dma_open(),
stream will be freed, but stream->list will not be removed from
adata->stream_list, then list traversal may cause UAF.
Fix by adding the newly allocated stream to the list once it's fully
initialised.
Fixes: 7929985cfe ("ASoC: amd: acp: Initialize list to store acp_stream during pcm_open")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
